300 °C for 3h max.)
Materials and surfaces
Splitter frames made of galvanised sheet steel
Absorption material is mineral wool
Mineral wool
To EN 13501, fire rating class A1, non-combustible
RAL quality mark RAL-GZ 388
Biosoluble and hence hygienically safe according to the German TRGS 905
(Technical Rules for Hazardous Substances) and EU directive 97/69/EG
Faced with glass fibre fabric as protection against erosion through airflow velocities
of up to 20 m/s
Inert to fungal and bacterial growth
